Hit a few sets of light squats tonight with what I would consider success! After deload deadlifts I did 135x8x3. I made quite a few adjustments to my setup and form:
1. took a little wider stance
2. took a wider grip
3. concentrated on sitting down instead of back
4. forced knees out all the way down into the hole and held them out as best I could

I typically cannot hit depth with this light of weight on the bar. I was consistently able to hit below parallel on every rep. And I felt like I was much more upright than normal! Friday is deload squat day so I will try to get some vids for critique
